Size Pipe Based on Drainage Fixture Units

I’m looking to get the pipe to automatically size itself depending on the number of units it’s responsible for. How would I go about this? My main hang-up is getting the pipe to read what fixtures they are connected to.

Hi @jeconlon, can you please show us the graph of what you’ve done so far?
And please read the guidelines on how to ask a question in this forum :-).

Revit can already calculate the connected fixture units in a pipe. You just need everything connected properly and with the right calculations on.

It can if you are from America… Other countries need work arounds
